Title: Can black holes convert matter to anti-matter?
Post by: Brennan Cavanah on 30/09/2011 16:30:02
Brennan Cavanah  asked the Naked Scientists:
   
I just wanted to thank everyone first of all, love the programme (http://www.thenakedscientists.com/HTML/podcasts/).

My question is, is it possible that black holes are matter to anti-matter converters, and white holes are anti-matter to matter converters?




What do you think?

Well I'm surprised at the first two answers as they are definitely non mainstream.
This is a difficult question to answer in this thread as it involves non-mainstream ideas.

If matter and antimatter both go forward in time, then they will gravitationally attract each other and the answer will be no. 
If, on the other hand matter and antimatter go in opposite directions in time, then they will gravitationally repel each and the answer will be yes.  The latter is the answer that I personally favour but is non-mainstream.

If matter and antimatter gravitationally repel each other.  Of the pair particles created within the event horizon of a matter black hole, the gravity of the black hole will sort the particles.  Matter particles remaining tapped and antimatter particles gravitationally expelled, probably along the lines of the poles and at relativistic velocity.  This way a matter black hole will recycle all of its mass into antimatter. 

It follows from this that towards the end of the universe, if all or most of its matter is contained within one or more black holes then they will recycle that matter into a new antimatter universe.  This is definitely not a mainstream view but it does appear to follow on from the above.
